IMHO, there are few true photographer's shops anymore.
But if you to go to a good formal camera store that you can walk into and talk to someone human, Hunts Photo and Video has a shop in Manchester.

They are knowledgeable and can help with most anything.
Sorry that I don't know if there is (or is not) anything in or near the lakes region.
